Stop-Start

Most Fuel-Efficient Hybrids

Find out which hybrid cars get the most miles per gallon.

A stop-start hybrid is the simplest form of hybridization, if one wants to classify it as a “hybrid” at all, or merely an aid to efficiency. Automakers are putting this technology not only on gas-electric hybrids, but even straight internal combustion vehicles to save fuel. The engine does not need to run at a stop, and the engines are engineered so restart does not adversely affect their lifespan.
